Bio
I grew up in Minnesota, got a degree aerospace engineering from Iowa State University, then went to work in the flying objects business in northern California. I launch things into space that may or may not come back down.
Fun Fact: Because of the fortuitous timing of my move from Minnesota to California, my life was subject to a weird nexus of showbiz and politics: in two different states I lived under governors who were cast in the movie Predator.

A sextant is a nautical tool used in celestial navigation--by finding a known object's altitude (the angle between the horizon and the sun, say) at a known time (noon, say), you can calculate your latitude on the Earth's surface.
